First of all would like to thank the community for bringing so much information !

I've been trying to install iatkos L2 for 2 days but I am now stuck and I really need your help(ps:I looked for answers on every single website )

I have a toshiba p750 (intel core i7 ; GT 540M/intel HD3000)

The problem was that I couldn't boot after installation (with chameleon) I got stuck on the apple logo, when I used -x I could see it recognised a 450M (I didn't install any vga kext to avoid that )

So I tried -x ; graphicsenabler=yes & no

I tried to reinstall iATKOS L2 with chimera 1.6, which is a better option apparently for my graphic card, I didn't install any vga kext again

Right now when I use GraphicsEnabler=No it looks like everythings work fine, I can turn on and off the volume by pressing the buttons on my laptop, the wifi led is also turning on & off,there's a music that turns on (meaning the installation was a success??) but the problem is that I can only see that apple logo. In my opinion it is definitly a problem coming from the graphic card(s) but I am not sure and I really don't know what to do right now I thought that without any vga kext it would recognise the intel HD3000 immediately and work fine

Any idea, suggestion?

Thanks in advance, I really like the spirit of the forum (opensource forever ) and it would be a pleasure to help you guys in the near futur (why not ?!)

I went on Windows and I installed MacDrive8, I just had to delete all the apple-intel kexts that I already had !!!

I didn't sleep for 2 days and it was actually so simple ... I'd like to thank you guys, even if you just gave me a quick answer but, it helped me to understand the problems I was facing and to figure out a solution

Check the smbios. Laptop requires macbookpro 8,1+ board id set. If it;s the board id of a Mac Pro then the intel graphic kexts won't get loaded
If it's a Mac Pro change the SMbordproduct to Mac-94245B3640C91C81 SMproductname to MacBookPro8,1 (or 2 or 3) and SMfamily to MacBook Pro

I forgot to ask, do you have a 3D screen? Usually laptop owners with 3D screens can get the nvidia card to work.

Awh too bad, you're stuck with the Intel one like myself.

In my smbios the SMfamily is MacBook Pro with a space. I'm not sure wether it makes any difference but beside this your smbios is fine. As for the kexts, there's no need to use custom ones, the chameleon boot loader handles the injection so it works natively with the already present kexts. Using other "modified" ones may actually break.

What error do you encounter now? I forgot to ask (again) do you have a full HD screen or a HD screen? (FHD = 1920x1080) FHD Screens needs dual link patch applied in order to load the kexts properly.

So I changed to MacBook Pro it didn't workThen I deleted all the appleintel kexts and I kept that smbios,,, didn't work eitherSo this smbios is probably not compatible with my laptop, I changed it to the old one and now I can boot (of course I still don't have any appleintel kext)

I forgot to ask (again) do you have a full HD screen or a HD screen? (FHD = 1920x1080) FHD Screens needs dual link patch applied in order to load the kexts properly.

It's weird indeed that you can use MacPro to boot but not the appropriate MacBookPro one with the kexts loaded. Update your boot loader, restore the original kexts don't forget to rebuilt kextcache (kext wizard is a good tool to do that) then set the smbios back to 8,1 and try again.

Hey Doix!!Thank you so much! I installed enoch, and it's muuuuuch better!

I also installed a 540m gt kext but it's a bit weird, it still shows a resolution of 1024x768 in the parameters (I'm sure it changed to 1366x768) and I don't see anymore the intel hd3000 in the system information. I don't use any of the intelhd kexts. I have to find a way to "disable" the intel graphic card (picture 2), so that the nvidia can be enabled

Ps: It's in french 12

(sorry for using imageshack but I didn't find how to upload pictures I'm such a nooby )I changed the smbios to the macbookpro 8,1 and I can boot now

You're welcome... but remove the GT540m kext and reinstall the Intel HD ones.. trust me I know what i'm talking about. You can't get the nvidia to work under a locked bios or without heavy programming skills.

Best pray to find a unlocked bios (if it's even unlockable) then set the Nvidia GPU as primary in the bios. Note: not all bioses, even unlocked, allow users to do this, some - if not most - just disable the laptop screen completely.

Also, battery life will be pretty low due to having both cards active, temps will be a bit higher as well but this depends on the hardware position.

Alright, so I deleted the nvidia kext and I reinstalled the appleintel kexts as you told me (I really don't want to touch the bios ). I checked on a thousand forums what was wrong, and I checked if the device id in the kext's info was correct etc... but nothing is changing I still have 64mb and "apparently" a resolution of 1024x768...

Do you know how it is possible to save a log (of the verbose mode screen)?
I found out I probably have a problem with my processors (I can't use more than one/cpus=1) and it's scares me off ! That could also help me to understand why the kexts are not loading.
